ИСТИНА

This invention relates to the field of producing low-density, heat-conducting materials based on thermally-expanded graphite, which can be used for conducting heat and also for distributing heat, inter alia, in a range of high temperatures. The present method for producing a low-density, heat-conducting material from thermally-expanded graphite is characterized in that it includes the following stages: (A) producing particles of thermally-expanded graphite by heating particles of hydrolyzed graphite nitrate at a specific heating energy equal to or greater than 4.7 kJ/g in an atmosphere of products of the combustion of liquid or gas fuel in air with an air-fuel equivalence ratio of »=0.8-1.1; and (B) subsequently compacting the above-mentioned thermally-expanded graphite to a density of from 0.03 to 0.1 g/cm 3 . The invention makes it possible to produce a low-density, heat-conducting material with high flexural strength and a high modulus of elasticity, which is characterized by the absence of acidic corrosive additives.
